Unfortunatly Sidney did not attend today. He was admitted to hospital yesterday with urinary retention aggravated by constipation.
The most common cause of urinary retention however is benign prostatic hyperplasia.
Sidney may have had any of the following differential diagnoses which can also cause retention.
He is also on amitriptyline which is in the anticholinergic and alpha-adrenergic agonist group of medicines. These can lead to urine retention (see chart)
Sidney’s medicines may need a review
